MANUFACTURE OF PASTED TUBES FOR CIGARETTES.

:iPECIFICATION forming part of Letters Patent No. 773,367, dated October 25, 1904.

Application filed March 18, 1904.

To all whom it may concern:

tion.

This invention relates to improvements in the manufacture of pasted tubes for cigarettes. Heretofore the pasting has been done by passing the superposed edges of the paper,

one of which is pasted, between the surface of a support within the tube and that of a corrugated roller located at the outside and pressed toward the said support. It frequently happens with this arrangement that the paste expulsed by the pressure becomes deposited on the inner support to such an extent that the passage of the paper tube is prevented. This inconvenience is avoided by the present invention, for the reason that the pressure required for the pasting operation is produced by two means located outside the paper tube without the interposition of a supporting-surface within the latter. The obstruction of these means by the paste forced out by the pressure is therefore no longer to be feared, and if such obstruction does occur for any reason whatever it can be removed at once, because as the pressing parts are located outside the tube they are always easy for access and easy to keep clean. This device has the effect of flattening the tube between the two pressing parts; but the cylindrical form of the tube is easily restored immediately after the pasting by means of a suitable device located beyond the pressing parts.

In the accompanying drawings, which show, by way of example, one form in which this invention 'may be carried out, .Figure l is an elevation of a spindle having two rollers. Fig. 2. is a plan of the same, the upper roller being removed. Figs. 3 and 4: are cross-sections on the lines AA and B B, respectively, of Fig. 1 looking in opposite directions. Fig.

Serial No. 198,857. (No model.)

5 is a cross-section, also on the line B B, showing the action of the rollers on the pa- 5 per tube.

The spindle used comprises a rear portion aof cylindrical shape and a forward portion 7) of horizontally flat shape, the shapes of the two portions gradually merging. The flat portion 6 has a longitudinal aperture or opening 0, the width of which is somewhat larger than that of the rollers (Z and e, which are located above and under the spindle. The lower roller is carried by a lever f, subjected to the action of an adjustable spring g, so that it is pressed with greater or less force toward the upper roller. The spindle is supported in the usual manner, as shown at h. The parts 71;, which extend on each side of the 5 opening 0, may be somewhat reduced at the starting-point, as shown at m, in order to easily regulate the width of the spindle near the rollers, according to the exact width to be given. to the paper tube.

When a continuous strip of paper is drawn along the spindle by the pull exercised by means of the rollers (Z 6, for instance, which are then connected by toothed wheels and actuated mechanically, the said strip first passes 75 in front of a pasting device, which pastes one of its edges, then through ashaping device z'of well-known form, which brings the two edges of the strip opposite one another. Thence the strip, now in the form of a tube, moves forward above the opening 0 and passes between the rollers (Z e, which flatten it, as shown in Fig. 5, in pressing the two edges of the strip one onto the other, so as to paste the same together. Beyond the rollers the flattened 5 tube is restored to its cylindrical shape by the action of an extended portion of the spindle, which, as here shown, consists in two diverging blades j, fixed to the end of the spindle, the outer surface of the blades being convex. 99 Instead of such blades there may be used an extension of the spindle, either hollow or solid and of any suitable diverging shape. Likewise there may be used to expand the flattened tube any other suitable shaping device, independent of the spindle or not and arranged pendent the spindle may be terminated on this side of the rollers by an end of any suitable shape, although it is preferable to maintain the two side parts Z? to guide the tube at its passage between the rollers.

We claim 1. A device for pasting a continuous strip of paper in the shape of a tube, comprising a spindle, two rollers so arranged on opposite sides of the spindle as to be pressed the one against the other, and a shaping device.

2. A device for pasting a continuous strip of paper in the shape of a tube, comprising a spindle having a shaping dex'ice for the strip, a flattened portion with an opening in the same, and two rollers both so arranged as to partly enter into the said opening and to be pressed the one against the other.

3. A device for pasting a continuous strip of paper in the shape of a tube, comprising-a spindle,two rollers so arranged as to be pressed the one against the other approximately coincident with the axial line of the spindle, a lever carrying one of the rollers, a spring acting on the said lever, and a screw to regulate the tension of the spring.

4. A device for pasting a continuous strip of paper in the shape of a tube, comprising a spindle having a flattened portion, an opening in the said portion, and an expanding device of diverging shape fixed at the end of the fiattened portion, and two rollers so arranged as to partly enter into the said opening and to come in contact the one with the other on a line substantially coincident with the axial line of the spindle.

5. In a device for making tubes, the combination of a spindle having an opening therein, and two rollers arranged on opposite sides of the spindle and projecting into said opening; said spindle having a spreading device thereon consisting of two diverging blades.

In testimony that we claim the foregoing as our invention we have signed our names in presence ol two subscribing witnesses.
